This is a problem with several 'slow' films used in photodocumentation.
Using a 'standard' 35 mm setup, say a 8.5x11" original, we use an
f-stop of 11 for 1 sec. Your mileage may vary, so you should bracket
around that (say, f4.5, f8, f11, f16, f22, all for 1") and see which
exposure gives you the best results under your conditions. It will
vary a little depending on the reproduction scale (i.e. size of
original) and your lighting setup.
